3 ROLLER BEARING SERIES WINCH MOTORS 31/51/76 Permco produces three series of roller bearing gear winch motors. These have been speci cally designed for powering winches and other similar applications that require high starting torque and smooth power distribution. Our conventional motor design uses a ten-tooth gear, which provides good performance above 4. However in certain applications, start up torque and slow speeds (below 4 ) are very important. This is where the winch motor thirteen-tooth count gear comes into effect. It provides: 1- Improved Starting Torque 2- Smoother Low Speed Operation 3- Extremely low torque ripple Above 4, torque, speed and ef ciency approach our standard motor models with the 1-tooth gear design. The W series gears are a computer-assisted design that optimizes displacement, tooth strength and smooth power application. Displacement of the W76 is 4.1 cubic inches/rev, per inch of gear width, the W51 is 2.57 cubic inches/rev, per inch of gear width and the W31 is 2. cubic inches/rev, per inch of gear width. The typical W series motor (1.5 inch width or larger) has a minimum starting torque of about 8% of the theoretical and can be smoothly operated at speeds as low as 1. The W31, W51 and the W76 winch motor are available in the same con gurations, gear widths and mounting options as Permco s standard M31, M51 and M76 motors. Permco s Engineer s Handbook may be used in selecting the options and coding. To order, please start the part number with a W ; this represents a winch motor application. If you are building the units from spare parts, please use the special winch motor thrust plates, winch motor ring seals and winch motor gears. Copyright 26 Permco Page 3 of 1 1/27/26
